Localized surface plasmon resonance based biosensing
Expert Review of Molecular Diagnostics, 2018Bioanalytical sensing based on the principle of localized surface plasmon resonance experiences is currently an extremely rapid development. Novel sensors with new kinds of plasmonic transducers and innovative concepts for the signal development as well as read-out principles were identified. This review will give an overview of the development of this

Near-field photonics: surface plasmon polaritons and localized surface plasmons
Journal of Optics A: Pure and Applied Optics, 2003Surface plasmon polaritons and localized surface plasmons are discussed in the context of photonic applications. Near-field imaging of scattering, reflection, interference and localization of surface polaritons is reviewed, and approaches for the implementation of elements of surface polariton optics are presented.

Integrated localized surface plasmon waveguides
Applied Physics A, 2012Compact plasmonic structures made of gold nanoparticles chains are inserted on silicon optical waveguides. We show that silicon-on-insulator waveguide TE mode energy can be almost totally transferred in a 5 gold nanoparticles plasmonic chain, and that this short chain can also behave as a waveguide.

Localized Surface Plasmon Resonances in Aluminum Nanodisks
Nano Letters, 2008The plasmonic properties of arrays of supported Al nanodisks, fabricated by hole-mask colloidal lithography (HCL), are analyzed for the disk diameter range 61-492 nm at a constant disk height of 20 nm. Strong and well-defined (UV-vis-NIR) localized surface plasmon resonances are found and experimentally characterized with respect to spectral peak ...

Selective amplification of spoof localized surface plasmons
Applied Optics, 2019Here, selective amplification of spoof localized surface plasmons (LSPs) has been demonstrated, where two coupling stubs gathering energies from the spoof LSPs resonator are designed on the back of the corrugated metal-insulator-metal ring resonator. The quadrupole mode is selected and amplified through the coupling stubs and the incorporated amplifier

Localized Surface Plasmon Resonance Spectroscopy and Sensing
Annual Review of Physical Chemistry, 2007Localized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles is a powerful technique for chemical and biological sensing experiments. Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes.

Potential-Scanning Localized Surface Plasmon Resonance Sensor
ACS Nano, 2015Localized surface plasmon resonance (LSPR) sensors based on plasmonic nanoparticles attract much attention recently. Here we propose a new class of LSPR sensor, that is, a potential-scanning LSPR sensor, in which electron density of the plasmonic nanoparticles is controlled by potential scanning.

Localized surface plasmon sensing platform
SPIE Proceedings, 2007Surface plasmon resonance (SPR) biosensors based on attenuated total reflection (ATR) have been widely used in biochemistry and genetic engineering, because it is a sensitive and label-free method. The dimension of the sensing probe is millimeters or more, so that the required amount of a sample solution is more than 100 μL even if a micro chamber ...
